HOLDER FOR LAMPS.

Specification of Letters Patent No.

one Form of the same, while Fig. 1%. is a trout elevation of another mode at constructing it.

lt is well known that the common method of balancing chandeliers, burners or lamps, which are so hung or suspended as to be capable of being raised or lowered to difterent altitudes is by means of weights connccted to chains carried over or around guide pulleys. Such mode for many reasons is objectionable, and particularly on account of its being attended with more or less liability of breakage of a chain and a consequent fall of the lamp, chandelier, burner. or counterbalance or both. My improvement is intended to overcome the objections to such a mode of counterbalancing a light.- ing apparatus, and is particularly useful with reference to the extension gas tube or chandelier supporter for which Letters Patent were granted to me in September 1857, an apparatus of such nature being particularly represented in Fig. A of the accompanying drawings, in which figure, as well as in Fig. l3, 1) exhibits a system of crossed and jointed levers usually known by the name of lazy tongs. In Fig. A the said system of levers is shown as having a sy tern, E. of jointed tubes connected with it substantially as represented in my said patent of StEPt'QllllNl', 1857. l urthermore, the said Fig. A exhibits the extension apparatus as supporting a lighting apparatus or chandelier, F, having two or more burners c, c, the conduit tube, c, of such chandelier or lighting apparatus being suspended from the lower joint, (7, of the system of the lazy tongs In Fig. B a rod, 6, takes the place of a tube and is suspended from the joint, (I, of the lazy tongs D, I). This rod, e. may be made to support in a proper manner one or more lamps, G, G, or other articles.

The mode in which I counterbalance an apparatus as above described may be thus 22.664, dated January 18, 1859.

explained: The two levers. i. 1', of the upper joint, (I. I extend beyond the said joint as shown at i", 1", in Figs. A and I3. and joint their upper ends respectively to the lower ends of two connecting bars or links. In, 1c, the upper ends of the said bars. being jointed to a slider, encompassing and playing on a suspension rod or conducting tube, m. A weight, I), is adapted to the tube, In, in such llltlllllt as to be capable of slid ing freely thereon and with the slider. upon which said weight rests or to which it is to be atlixed as circumstances may require. This weight,through its action on the levers. 2', I. through the slider, 7, and connections, Z. should be sutlicient to counterbalance the downward draft of the lazy tongs or the extension gas tube apparatus or the same and whatever may be suspended therefrom and so that however the lazy tongs may be contracted or extended its parts will be. maintained in their positions by such counterbalancing apparatus or means. Further more in order to steady the rod or tube. c. the lowermost bars: ot' the lazy tongs may be extended across on another at the joint. (I. so as to "Form two levers. 0, 0, whose outer ends may be jointed respectively to a slider. p. by connection links, f, y, the slider having the rod or tube. c, passing through it so as to permit the slider to be moved Freely in a longitudinal direction on the tube. Dun ing expansion of the lazy tongs, the slider will be traced downward on the rod or tube. c, aml with the connections, f, 1, and levers, o, 0, will serve to support the said tube .or rod.

It will be evident that instead of a weight. b, a spring might be employed to act on the slider, Z, and cite-ct the counterhalaneing of the appa atus. Such however would be but a mechanical equivalent for the weight. l urthermore, in case the weight, I), should be attached to the slider, Z, the apparatus may be used in reverse, that is to say, it may be inverted in such manner as to cause the weight to depend from the levers, i, 1', the rod or tube m. of the weight. being fixed to a table or other body. In this way. the weight would pull on the levers. i, 1', instead of pushing them, and the apparatus could be extended upward. By such an arrangement of it, it coald be made to extend out. of a recess, and to fold back or contract therein as occasion might require.
